DESCRIPTION

The AIC431, TL431A and TL431 are 3-

terminal adjustable precision shunt regulators

with guaranteed temperature stability over the

applicable extended commercial temperature

range. The output voltage may be set at any

level greater than 2.495V (V

merely by selecting two external resistors

that act as a voltage divider network. These

devices have a typical output impedance of

0.08 . Active output circuitry provides a very

sharp turn-on characteristics, making these

devices excellent improved replacements for

zener diodes in many applications.

The precise

ance of the AIC431 makes it possible in

many applications to avoid the use of a vari-

able resistor, consequently saving cost and

eliminating drift and reliability problems asso-

ciated with it.
